IMPROVEMENT IN coRN-PLANTERS'.

Specification forming part of Letters Patent No. 139,269, dated May 27, 1873; application filed March s, 1873.

To all whom it may concern: to graduate the charge of seed putin a hill. Be it known that I, HIRAM A. SHARP, of The traversing plates N` and P, Fig. 4, Harlem,Glay county,in the State of Missouri, have their rear ends fastened to the plate Q., have invented certain new and useful Improvements in Planters for Corn and other Seeds 5 that its edges traverse in the grooves e following to be a full sides A. The rear end of this plate is forked hereof, reference being so as to pass each side of the wheel G, and on one of the forks there is a acted on by the tappet of my invention-conplates forward at the proper r construction, combinathe seed, and then the spring T, fastened to t of devices forming the the' side A, acts against th which is made wider, than the othertwo, so

roller, R, which is S, to traverse the time and drop e lug U on the plate P, which has a f the hole W in of the hopper; and the plate N, so that as the two plates N and P d plan of the feedingare pushed forward the plate N shuts the seed In the above-mentioned drawings, A A are through the hole X into the side pieces of and C the rear en the frame,B the fo d, ,made in the form shown, `or in such other form as will answer the pury and firmly fastened together to form a it, with a coiled spring aroun to which the other parts are presses the block forward against a stop in ted. D is the fore axle prothe slot. But when the plate N is pushed l vided with two wheels, E E, and F is the rear wheel, Gr, which has prostron g frame, fastened or connec axle provided with one to turn in boxes fastened to the under side of The scraper end C, is provid as to clear the si and the tread o the edges of the ened by screws K.

eels E E, opposite each unbroken and is planted in the next hill. ble the operator to plant the block was held rigidly in its place it would that the rows will be at a right break and out the seed in t that it may be cultivated caught, and thus waste much Both of these axles are arranged a thin plate, c, with slots in it screwed on the top of the plate N to cover the block u and I, fastened under the coiled spring. There is a hole, d, in the plate ed with scores and prongs so P, by the fore end of the plate Q, shown des of the projecting points by dotted lines in Fig. 4, to let any dirt or f the wheel G. The inner seed fall out that may get between the plates. A A are grooved to receive The furrowing-runner e, shown partly by dotned in the fore end r the axle D and is with a space or h which the seed plate J, Fig. 3, which is fastted lines in.Fig. l, is faste This plate has a hole, L,

re end, ground. There is a slot in the plate N in rear of the hole W, .the same width of the hole, with a block, a, and pin b, fitted to traverse in d the pin which ed catches between dge of the block a, the spring,

forward and a kernel of se the slide M and the lower e oints on each edge of its periphery the block a stops and compresses t it from slipping as the planter while theplatemovesforward, so as not to break This rear axle F 4carries two markor crush the seed, so that when the plate N i in g-arms, H H, which make marks across the traverses back the seed falls into the hole L tracks of the fore wh deposit of se his field so angle to one another,

wo when it was seed. There is B, .and extends down unde in itl to receive the charge of seed to be dropprovided with two wings, c', ped, which holemaybe varied by the slide M opening between them throng falls to the ground. The win gs are provided with slotted arms f, which are fastened to the sides A so that the runner e may be adjusted higher or lower, as desired. The coveringscrapers gare connected by springs to thewings of the furroWing-runner, so as to yield and open when a clod of earth gets between them and let it out, and not dra-W it along to displace the seed dropped before it is covered. There is a tube in the plate l1., right under the hole L in the plate J, to conduct the seed down between tihe furrowng-Win gs when it is dropped, the plate hbeing fastened to the sides A. There is a bar fastened across the sides A to carry the scrapers 7c, which clean the fore Wheels E. The handles l lare fastened to the tops of the sides near theirrear ends.

I claiml.l In combination with a seed-delivering apparatus constructed with two slides, and l?, one traversing above and the other below, the perforated stationary plate J, the movable block a, constructed and arranged to operate substantially as described, for the purpose set forth.

2. The marking-arms H H, arranged on the rear axle F, to mark in the tracks of the fore Wheels E so that the marks Will not be obliterated by a shower of rain.

3. The spurs or projections on the Wheel G, arranged each side of the tread of the Wheel, in combination with the scraper I,.provided with scores and prongs to clear projections and tread of the Wheel.
